With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully. described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a longitudinal sectional view. Figure 2 is a sectional view on line 2-2 of Figure 1.

Figure 3 is a sectional view on line 3 3 of Figure 1.

Figure 4 is a sectional vievv on line l--l of Figure 1.-

Figure 5 is a detail sectionalvievv through the cap "and shell.

Referring to the drawings 1 designates the hub flange having the collar 2 in which the end ofthe axle (not shown) extends. The

` collar is provided with a pair of arcuate ribs 3, the Vends of which are spaced a sufficient distance to provide passages l? the ends Columbusyinthefcounty' of Franklin and l State of Ohio, have` invented neur and useful l ImprovementsinHub-Gap-Attaching Means,-

of said ribsconstituting stops 5,-the purposeoftvhich will later appear.Y

The hub fcap may be of anysuitable design and includes 'a domev? provided vvvith Wrench` engaging lfaces. The; rnn1 .of #thisl cap=differs from the custom-arycap inthe provision of thediametricallydisposed 'arcuate flanges 8,3 Whichare of 'such-length as to pass'freely'throughlthe passages when. applying or removing 4the cap.

The :dome: 7 "has Asuitably#.HXedl interiorly i.

thereof a diskS), saidldisk beng^provided`- with a--pair of ldiametrically opposed seg.` ments 10,` the: faces of; Whichjare beveled in s opposite' direc-tionalv These segments are provided with recesses 11, the purpose of Whichwill appear later'.

Mountedwvithin" the cap 6 isfa steel shell 12ivhich includes'a crovvn lfadapted to." extend a spaced distance finto the dome 7,'

said shell including :an annular Asea-tvl adapted to tightly` engage the rim` of the collar 2 when the cap is in its operative posi.-`

tion. The outer edgeof the shell terminates inA soi a rim `llland is providedawvjith'diametrically opposed longitudinally curved Wings 15, they ends' of: which being adapted toicontact With the stops o when said Wings `occupythe passagesffl: and J vvhenv the f cap'` `1s. 1n place,

said stops serving '.toxprevent.rotation `of fthev shell: Itl :will be `observed that theshell` is of substantially the same general contour las the capziso ias tofit neatly therein.;

A disk 16 is suitably vsecured to the upper surface of the crown 13 of the shell and like the disk 9 is provided vvith a pair of oppositely beveled segments 1T adaptedto slidably engage the segments 10 of the disk 9. rlhe segments 17 are provided with lugs 18 adapted to snap into engagement' with said recesses of the segments l0 when `the cap 6 has been rotated to its [inal or operative position, thereby preventing accidental disengagement ofthe cap.

In operation the cap 6 is placed relative the collar 2 to permit the flanges 8 to pass through the passages L1 until they rest upon the annular shoulder 19 carried by the collar and aline with the grooves 2O formed between the shoulder and ribs and at which time the Wings 15 occupy the passages With their ends engaged with the 5. Upon rotating the cap in a clockwise direction the flanges 8 Will enter the stops grooves 20, but owing to the fact that the wings l5 are interlocked with the stops 5 the shell is held against rotation. Continued rotation of the cap will cause the beveled faces of the segments l0 to ride upon the similar faces of the segments 1T, thereby causing the flanges S to tightly engage the ribs 3, whereupon the shell l2 is subjected to pressure and forced downwardly until the seat 13 tightly engages the rim of the collar 2 to provide a liquid and dust tight metal to metal connection, thereby eliminating the use of gaskets or the like. Further rotation of the cap will cause the lugs IS to snap into engagement with the recesses 1l, thereby preventing accidental rot-ation of the cap in a reverse direction. Owing to the inherent resiliency of the shell l2, t-he beveled faces of the segments l0 and 17, when fully engaged will hold the seat 13 tightly, and to some extent yieldably engaged with the rim of the collar 2. It will be of course understood that a suitable wrench will be used in connection with the dome .7 to remove or replace the cap.

To limit the rotation of the cap in either direction a pin 2l is placed in one end of one of the grooves 20 and with which one of the flanges 8 contacts.

From the foregoing description it will be seen that a structure is provided which is more particularly designed for use in connection with hub caps, but can be used with equal success in connection with radiator caps, gasoline tanks and in fact any place wherein it is desired to obtain a liquid and dust tight joint without the use of threads.

lVhat is claimed is:

l. The combination with a hub collar, of a cap, a shell mounted in the cap, means for interlocking the shell with the collar to prevent rotation thereof during rotation of the cap, the saine means serving to interlock the cap with the collar, and means for imparting endwise movement to the cap and shell when the cap is rotated, thereby causing the shell to seat upon the collar and the cap to bindingly engage the cap interlocking means.

2. The combination with a hub collar, of a pair of ribs carried by the collar and having spaced ends constituting stops, a cap having flanges for co-operative engagement with the ribs, a shell mounted in the cap and provided with wings for interlocking engagement with the stops to prevent rotation of the shell during rotation of the cap, and means for exerting endwise movement of the cap and shell in opposite directions to cause the flanges to tightly engage the ribs and the shell to seat upon the rim of the hub collar.

3. The combination with a hub collar, ol a cap for interlocking engagement with the collar, a relatively resilient shell mounted in the cap, means for interlocking the shell with the collar to prevent rotation thereof during rotation of the cap, and means operable upon rotation of the cap to more the cap and shell endwise to flex the latter for yieldable engagement with the rim of the collar.

4. The combination with a hub collar, of a cap having oppositely beveled segments mounted therein, a shell mounted in the cap and having beveled segments for co-operation with the first named segments, means for interlocking the shell with the collar to prevent rotation thereof when the cap is rotated, said segments serving to move the cap and shell endwise in opposite directions to cause the shell to tightly engage the rim of the collar and the cap to interlock with said collar.

In testimony whereof I have hereunto set my hand.
